' E ACHABLE HEEL.

Applicationrfiled August 18, 1921. Serial No. 493,442;

' To all whom'z't-may concern:

' Be it known that I, MAXIMILIAN J URISS, a subject of the King of GreatBritain and Ire and, residing at 148 Ghuznee Street,

Wellington, New Zealand, have invented new and useful Improvements inDetachable Heels, of which the followingis a specification.

My invention relates to improvements in detachable heels or heelprotectorsmade of rubber or-leather, or rubber and leather, of the typein which the protectors are removed when worn away and replaced bynewones.

According to the present invention, I utilize preferably the metal studswhich are moulded in the rubber protectors on the un derside one at theback and the other at the side. These studs engage corresponding slotsin metal plates secured to the permanent heel. The slots are wide at oneend and narrow at the other end to enable the stud to enter the widepart, slide freely and be adjusted in position in the narrow end of theslot, which is placed towards therim of the heel. To prevent anymovement of the stud in the slot when adjusted a button mould in therubber protector is adapted to engage a spring dome or the like in thepermanent heel. The arrangement of the studs engaging. the slots and thebutton en: gaging the spring dome forms a triangle the apex being thestud and slot lying vertically, and the base being the other stud andslot lying horizontally with the spring button. 35 As an alternative,plates with bayonet joints may be substituted for the slots described.

eferring to the drawings, which form part of this specification, Figures.1 and 2 are views in elevation of the heel portion of a boot or shoeand the detachable heel pad or heel protector removed therefrom.

Figure 3 is a view showing the method of attaching the removable. heelor protector.

Figures 4 and 5 are side views partly in section of the heel portion ofa boot or shoe and the detachable protector.

Figure 6 shows a detail of a modification.

The detachable heel. or heel protector awhich may be made ofindia-rubber, balata, leather, leather substitute or a combination ofany or all of such materials, is provided on its underside with a seriesof studs or headed pins or the like secured to said heelpadinany-suitable manner. The heel por- 55' tion 6 of the boot or shoe(not shown) is provided with one or more recesses or slots into whichthe studs or pins engage. In the example illustrated in the drawings,the heel pad ais provided with a central stud 0 located towards'th'e:rear edge of the pad and with a second stud 0? located towards the frontandjonone side, whilst on the opposite side at the front is fixed a stud6 provided with a substantially spherical head 6 The heel portion 6 isprovided with recesses corresponding in position with the studs 0,61, 6,on the heel pad and each of these recesses is covered by an aperturedplate f, f 79 The plate f is located centrally towards the rear of theheel and is provided with a key-hole slot g, the circular portion 9 ofwhich is located towards the front whilst the longitudinal portion ofthe slot extends rearwardly towards the rear edge of the'heel. The plate7 is also provided with a key hole slot h which lies approximate in sucha position that a circle with the outer endof the slot 9 as the centrepasses -l ongit-udinally through the centre thereof. The plate 7 isprovided with a circular aperture k and beneath said aperture is locateda spring rm ofany convenient construction which co-operates with thespherical head 6 of the stud c in the manner of a press button. Theheads of the studs 0 and (Z are of such size as to pass freely throughthe circular portions of the key-hole slots but when said heads areslidden into the longitudinal portions of the slots the heads engagebeneath the plate and the studs are thereby secured firmly in position.

The heel pad or protector is attached in the following manner.

The head of the stud c at the rear of the heel pad is first passed intothe circular portion 9 of the slot 9 in the plate 7 and is then sliddenrearwardly until said stud is located at the rear end'of the slot. Thisposition is shown in Figure 3. The heel pad a is now rotated until thehead of the stud d is in a position to pass through the circular portionof the key hole slot in in the plate 7 and the heel pad is then rotatedabout the centre of the stud 0 until the stud d is pressed to the outerend of the longitudinal portion of the slot h. The spherical head 6 ofthestud e is now in a position in which, by pressure on the outersurface of the heel, the head of the stud may be pressed into the recessis, the sides of the spring m opening out to permit the head to pass andclosing in again to firmly grip the head and retain the same in thelocked position. The heel pad or protector is now firmly secured inposition and will not be likely to become accidentally detached duringwear of the boot or shoe.

The spring means employed to secure the stud e in position may be of anyother convenient construction. For instance instead of employing aspring of the spring-button type, I may provide a slidable strip forkedat its inner ends which passes through an aperture in the front verticalface of the heel, said sliding member being provided with a small headas indicated at n in Figures l and S which permits said member to bepulled out to release the inner forked end thereof from the head 6 ofthe stud e.

As shown in Figures 1 and 3, the plates f, f and f are secured to thebase of the heel proper by screws 0. I may however secure the plates inany other convenient manner or if desired, I may provide a single plate7) (Fig. 6) cut to snugly fit the base of the heel. This plate isprovided wit apertures or slots 9, h, and similar in shape and positionto the corresponding slots and apertures in the construction shown inFigure 1, the plate being secured to the base of the heel by screws orin any other appropriate manner.

The studs 0, (Z and 6 may be secured to the detachable heel pad in anysuitable manner. As shown in Figure 5, the stud c is provided with aflange 0 on its outer'end and with a shank portion passing through ahole in the pad, the outer end of the shank portion being provided witha washer or plate 0 snugly fitting in a recess a in the outer face ofthe heel pad. The recess a may be filled in with cement or any othersuitable material.

The studs 0, (Z and c on the pad a may be located at slightly greaterdistances apart than the corresponding parts of the slots 9, 7L, andaperture 72 so that when the heel is secured in position, the bending ofthe pad at the centre causes its edges to press tightly into contactwith the edges of the heel b.

By this arrangement the button and spring dome with studs cannot bedisengaged accidentally. The studs being on plates moulded in thedetachable rubber protectors or on plates secured by brads to leatherprotectors, there are no apertures in the same to collect dirt from theroads, thereby disseminating disease. My protectors are interchangeable,thus enabling the wearer always to have level heels. This is a greatadvantage, as uneven wear of the heel is very unsightly; and by changingonce a week the life of the heels is greatly prolonged. For the firstpair of detachable protectors only, a fiat leather heel piece with theslot plates and spring dome already attached thereto ready 1 ,asaaao fornailing to the heel of the boot, may be supplied in Order to save thewearer the trouble of fixing the slot plates and spring dome separatelyto the permanent heel and for the purpose of aligning with thedetachable protector.
